You don't say how long you'll be out. If you're still
traveling in August, the Indian Market in Santa Fe NM is
definitely worth a day or two.

If you need something earlier, you might go to the Spanish
Market. This year I believe it's July 30 and 31. Not nearly
as interesting as Indian Market, tho, and skippable in my
opinion. http://www.spanishmarket.org/

If you do go to Santa Fe, be sure to take the Turquoise
Trail from Albuquerque to get there. No festivals involved,
but a very nice drive. http://www.turquoisetrail.org/
